' SPINDLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 602,171, dated April 12,1898. Application led February 20,1897. Serial No. 624,391. (No model.) I

To @ZZ whom. it may concern:

Be it known that I, EPPA H. RYON, of Waltham, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Spindle-Supports, of which the following description, in connection with the accompanying drawings, is a speciication, like letters on the drawings representing like parts.

This invention has for its object the production of a novel spindle-support.

In this iny present invention the pintle of the spindle is placed in a bolster which isy rotated positively, it taking the spindle with it, and preferably I interpose a packing between the pintle and the interior of the bolster.

shoulder which cooperates with a notchor projection of the iiange on the spindle against which the base of the bobbin rests.

Figure 1, in partial vertical section, shows a spindle and a support therefor embodying my invention; Fig. 2, an external view of the bolster; Fig. 3, a section below the line a, Fig. l.

The spindle A, composed of a blade a andpintle a and of any usual or suitable length and diameter, is provided with aflange a2 of usual character on which rests the lower or head end of any usual bobbin. (Not shown.)

The supporting-case B is adapted to be secured to a spindle-rail in any usual manner.

The bolster C consists of a tube, preferably closed at its lower end, as at c, and provided above its end with an inclined or tapered surface c.

The closed end c is shown as made conical, and said end is represented as being sustained in and free to turn on a suitable rolling surface, the drawings illustrating a series of balls cl, held in a ball-case; but instead of the balls shown I may employ any other usual number or shape of balls or-other bearings commonly used in such positions.

The upper end of the supporting-case is shown as provided with a screw-thread ate,

into which,after the bolster has been putin the case B, is screwed the ring D, a series of balls or rolling surfaces d2 being interposed between the said ring and the said inclined surface of the bolster, said balls resisting the 6o strain of the band on the whirl E, which is set onto the top of the bolster, the pin or projection f, held in the whirl, entering a notch at the upper end of the bolster to thus so connect the whirl and bolster that when the band is put in the groove of the whirl the bolster Pwill be rotated, and the said projection entering a notch f2 in the flange a2 causes the rotation of the spindle with it. The pintle of the spindle entering the bolster is surrounded vof the hook has a sliding block provided with a lip Ah, which may enter any one of a series of notches h2 in the ring to thus hold said ring in its adjusted position.

Having fully described my invention, what 8o I claim, and desire to secure by Letters Patent isl vA bolster having an attached whirl, a

Ysurrounding support to receive said bolster,

a spindle having its pintle within said bolster and means to connectthe said whirl and bolster with the spindle in order that the latter may be rotated with'the bolster and its whirl, and ball-bearings interposed between the said bolster and its supporting-case near 9o said whirl to constitute a rolling lateral bearing for the bolster, substantially as described.

2. Abolster havin g an attached whirl, means tol sustain said bolster, a spindle having its pintle within said bolster, and means to conneet the said whirl and bolster with the spindlel in order that the latter may be rotated with the bolster and its whirl, anda packing interposed between said pintle and bolster, substantially as described.

3. A supporting-case, a bolster having at its exterior a tapered or inclined surface, a

IOO

ring surrounding said bolster, rolling surfaces interposed between said ring 'and the tapered orinclined surface of the bolster, and a whirl connected with and to rotate the bolster, substantially as described.

4. A supporting-case, a bolster having at its exterior a tapered or inclined surface, a rolling surface to sustain the weight of said bolster, a ring surrounding said bolster, rolling surfaces interposed between said ring and the tapered or inclined surface of the bolster, and a whirl connected with and to rotate the said bolster, substantially as described.

5. The supporting-case, its notched ring, a bolster having an attached whirl, and a spindle provided with a flange independent of and located above said Whirl, combined with a hook to overlap the said flange, and a movable lip to enter a notchin the said ring, substantially as described.

6. The bolster-case, a bolster therein provided near its upper end with an inclined or tapered surface, a whirl attached to said bolster, and a ring interposed between said tapered or inclined surface and the lower end of the whirl, combined with a series of balls or rolling surfaces interposed between said ring and said tapered or inclined surface, substantially as described.

7. A supporting-case, a spindle, a bolster having an inclined or tapered surface and ro- I tated in unison with said spindle, combined with a ring mounted on the supporting-case and a series of balls interposed between said inclined or tapered surface of the bolster and said ring, substantially as described.

8. A supporting-case anda spindle, a bolster in which the pintle of the spindle is inserted loosely, means to connect said spindle and bolster that they may be rotated in unison with a suitable packing interposed between said bolster and spindle, substantially as described.

9. A supportingcase and a spindle, a bolster in which the pintle of the spindle is inserted loosely, means to connect said spindle and bolster that they may be rotated in uni son, combined with a bearing in said supporting-case for the end of said bolster, and with a suitable packing interposed between said bolster and spindle, substantially as described.

In testimony Whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EPPA II. RYON.
